Muḥammad Mīr, poetically surnamed Soz, was the son of Sayyed Ẓiyā-ud-Dīn and a descendant of the saint Qutb ʿĀlam of Gujarāt. His ancestors came from Buḵẖārā to Delhi where Soz was born in 1133 A. H. at Qarāwalpūr. Mīr Soz originally wrote under the Taḵẖallus Mīr, but when Mīr Taqī became famous under that poetical name, he changed his name to Soz. The following verse is attributed to him due to this change:
کہتے تھے پہلے میر میر تب نه موئے ہزار حیف
اب جو کہے ہیں سوز سوز یعنی سدا جلا کرو

During the reign of Shāh ʿĀlam, Soz left his native city in 1191 A. H./1777 A. D. in a state of utter poverty. He visited Farruḵẖābād, Lucknow and Murshidābād in search of employment. At last he took up his residence at Lucknow and was befriended by Nawāb Āṣaf-ud-Daulah, who became his pupil in theart of poetical composition. But shortly after this, Soz died at Lucknow in 1213 A. H. at the age of eighty.
On the fly-leaf we find the following verse and a note apparently written in а different hand:
دعوی بڑا ھے سوز کو اپنے کلام کا
جو غور کیجۓ تو ھے کوڑی کے کام کا
دیوان میر سوز خرید قیمت سه مبلغ روپیه
